92 S10 vibration in gear?

[hutch_pt]

We have a 1992 S10 with 4.3 V6 and automatic transmissions. We are using the frame and drivetrain to put under a 1949 suburban. Anyways, the engine is running well, but when you put the truck in gear, it gets a noticeable vibration under your butt. Is this a common issue with the S10's or is it something different? Also, any ideas on what is going on? It shifts fine, and drives fine, but the vibration is present (only in gear, not when in park or neutral). I know that a vibration will only get worse, so any help is appreciated.

The S-10s have a transmission mount that can sag when it gets oil soaked. Once the mount is saggy the transmission will touch the cross member and you will feel a vibration. The Exhaust pipe touching the cross member can also cause this problem.

To check this sit in the drivers seat with the brake applied and the wheels chocked. Put the transmission in gear so you feel the vibration. Keep your foot on the brake and have someone jack up the transmission about 2 inches with a floor jack. If the vibration goes away you have pin pointed the problem.
